| 摘要： | Between 1998 and 2004, nine experimental whitetopping projects were constructed in Illinois and their field performance was evaluated. Five of these projects involved the rehabilitation of highway intersections and the remaining four were a rehabilitation of mainline pavements. The projects were constructed on U.S. Highways, Illinois State Routes, and County Highways. These projects included the use of ultrathin whitetopping, thin whitetopping, and bonded concrete overlays of brick pavers and concrete. This report explores the performance for all nine projects through the end of 2004. A summary of the construction methods has been included for each project as a quick reference. Detailed traffic volumes, visual distress surveys, and soundings of the whitetopping projects were used as performance measures. These values and tests were collected or performed on an annual basis where applicable. The performance of the mainline pavement rehabilitations has been excellent to date except for a few minor distresses in one of the projects. The performance of the whitetopping sections of the intersection rehabilitations has also been excellent. The performance of the bonded concrete sections at the intersection rehabilitations has been satisfactory. |
